Embodiment Construction
[0021] Such as figure 2 As shown, the manufacturing method of X80 pipeline steel spiral welded pipe adopts the X80 pipeline steel coil with a wall thickness of 21.4mm, and its chemical composition (weight percentage) is as follows: C 0.04~0.07, Si 0.15~0.25, Mn 1.68~1.78, Nb0. 04~0.05, Ti 0.01~0.02, Cu 0.12~0.22, Cr 0.20~0.28, Mo 0.10~0.20, Ni 0.10~0.20, P<0.015, S<0.005, N<0.006, Fe is the balance; made pipe diameter It is a Φ1422mm X80 pipeline steel spiral welded pipe, and the process steps are as follows:
[0022] 1. Uncoiling and leveling of X80 pipeline steel coils: Uncoil the X80 pipeline steel coils with an uncoiler and level them with a leveler;
[0023] 2. Edge milling: rough milling first, milling off the width of the plate edge by 5-10mm; then fine milling, as attached figure 2 As shown, the groove on the outer side of the pipe wall is the outer groove, the groove on the inner side is the inner groove 6, and the straight edge between the two grooves is the blun...
